KNIFE-SCOURER.

SPECIFICATION forming part of Lettersliatent NO. 651,644, dated June 12, 1900.

Application filed January 10, 1900. Serial No. 993. {No model.)

clear, and exact description of the'invention, such as will enable others skilled in the art to' which it appertains to make and use the same.

The invention relates to a knife-seourer.

The object of the invention is to provide a device of this character which shall be simple of construction, durable in use, and comparatively inexpensive of production and by means of which a single or a plurality of knives may be thoroughly and expeditiously scoured at a minimum expenditure of labor.

With this and other objects in View lthe invention consists'in certain features of construction and combination of par ts,which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective View of my,improved knifescourer, showing in dotted lines the knives support-ed in position. Fig. 2 is a longitudinal vertical sectional View. Fig. 3 is a fragmentary sectional View at right angles to Fig. 2. Fig. 4 is a detail perspective view of one of the knife-rubbers'.

In the accompanying drawings the same reference charactersV indicate the same parts of the invention.

1 denotes a suitable casing consisting ofthe side pieces 2, the end pieces 3, and a removable bottom 4, the said bottom being provided with lugs 5,by means of which the device may be screwed to a table, bench,or othersupport. The bottom 4 of the casing is preferably inclined on its upper face and slants to an opening 6 in the lower end of one of the end pieces 3 of the casing, closedby a slide 7.

, 8 denotesa series of vertically-disposed rubbers, each of which consists of a block 9,made of any suitable material, such as wood or metal, and covered with a soft rubbing-strip 10, preferably of leather. The upper end of each block is provided with a curved head 11 to facilitate the introduction of the blades of the knives between said blocks, andthey further provided with shoulders 12, which take under the longitudinal inwardly-projecting flanges 13, formed at the upper end of the side pieces of the casing, thus preventing the accidental withdrawal of said rubbers.

' 14 denotes bars fixed within the casing and provided with plate-springs 15, the energy of which is exerted to force the rubbers together. I prefer to fasten the middle rubber in fixed position to the casin g, so that each spring will act against the movable rubbers arranged between said spring and the stationary rubber, whereby a more positive action is secured in the operation of the machine when but one or two knives are being cleaned. The lower ends of all the rubbers are provided with a notch or recess 1G, which forms a longitudi' nal channel from end to end of the casingimmediate] y above the inclined bottom to permit of the emery or other abrading or cleaning agent after it has been used and sifted to the bottom of the casing to be removed through the opening 16- and be reused.

17 denotes the knife-supporting frame, which comprises the side pieces 18, which are adapted to slide between the end pieces of 'the casing and the bars 14 and are provided with vertical grooves 19, into which project screw-stops 20 to limit the vertical movement of said frame by coming in contact with the end walls of said grooves. The upper end of the frame is provided with a grip or handle 21, by means of which the frame is reciprocated. A horizontally-disposed bar 22 is connected to the side pieces of the frame ,inter-l mediate their ends and is provided with apertures 23 for the introduction of the knifeblades between the rubbers.

24denotes a comb-plate, the spaces between the teeth of which are alined with the apertures in the cross-piece. This comb-plate is provided with studs 25, which are journaled in bearings 26, secured to the side pieces of the knife-supporting frame, thus permitting the plate to be` swung from over the crosspiece.

27 denotes means for fastening the combplate in operative position. This means consists, preferably, of turn-buttons; but any other suitable fastenings may beused in lieu thereof.

When it is desired to scour knives, the

IOO

comb-plate is swung to one side to permit of the introduction of theknife-blades through the apertures in the cross-bar 22 down between the scrubbers. After the knives have been thus placed the comb-plate is swung over the cross-bar 22, with the fingers of said comb-plate engaging the holsters of said knives. The turn-buttons 27 are new swung down into engagement with the comb-plate, thus locking the holsters of said knives between the comb-plate and the cross bar. The handle 21 is now grasped, and by reciprocating the knife-supporting frame vertically the blades of the knives will be quickly and thoroughly scoured. Those portions of the blades immediately below the holsters which are not scoured by the rubbers may be scoured by the rubber-strip 2S, attached to one corner of the casing.

The emery orother cleaning agent is sprinkled upon the tops of the upper ends of the rubbers, works down between the sides of the same, and finally downupon the bottom of the easiu g. By tapping thee-asin g the emery will be shaken to the lower end of the inclined bottom and may be removed through the slide at that end to be reused.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my improved knife-scourer will be readily apparent without requiring an extended eX- planation.

It will be seen that the device is simple of construction, that said construction permit-s of its manufacture at small cost, and that it is exceedingly well adapted for the purpose for which it is designed.

It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrilicing any of the advantages of this invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is

1. In a knife-scourer the combination with the casing provided with an inclined bottom and provided with a discharge-openin g at one end, and spring-actuated rubbers mounted in said casing; of a reeiprocatory knife-supporting frame mounted to slide in said casing, substantially as and for the purpose set forth.

2. In a knife-scourer the combination with the casing and rubbers mounted therein and adaptedto engage the knife-blades; of a re- `ciprocatory knife-supporting frame mounted to slide in said casing, said frame being provided with a cross-bar formed with openings, aV comb-plate carried by said frame, and means for clamping the comb-plate against the holsters of the knives to be scoured, substantially as and for the purpose set fort-h.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- DGSSGS.
